On 28 August, WPP and its group companies submitted a memorandum of law to the Supreme Court of the State of New York to dismiss the lawsuit that NDTV had filed (on 26 July) claiming manipulation of TAM data.
The motion filed by WPP called NDTV's complaint 'a vain attempt at revving up media coverage and divert attention from the latter's declining viewership and its unsatisfactory financial performance in the last five years'.
According to the motion, NDTV's petition named some of the (petitioned against) WPP companies improperly. WPP also said the court of New York doesn't have jurisdiction over defendant Kantar Media (which it co-owns with Nielsen), since it is an Indian company with no presence in the United States.
